Android Network Programming with Retrofit and Kotlin

Connecting your Android app to the internet is a fundamental skill, but handling API requests, authentication, and data parsing efficiently can be challenging. Retrofit simplifies this process, enabling you to build robust, network-aware mobile applications. This text-based course guides you from the absolute basics of HTTP networking to advanced API integration in Android. You will learn how to configure network clients, manage headers, handle background threads, and parse complex JSON data using modern industry practices. What you'll learn: - Understand core HTTP concepts, RESTful API structures, and how Retrofit maps network requests to Kotlin interfaces. - Configure Retrofit clients with OkHttpClient, custom headers, logging interceptors, and caching strategies. - Perform asynchronous network calls using modern Kotlin Coroutines and handle loading and error states gracefully. - Implement authentication workflows, including token-based auth and OAuth flows for secure API access. - Manage complex data payloads using GET, POST, and multipart requests for uploading files and form data. - Integrate modern serialization libraries to parse JSON data efficiently into Kotlin data classes. The course begins with foundational networking terminology and basic Retrofit setup before moving into request methods, authentication, and advanced error handling. You will progress through written explanations, code walkthroughs, and conceptual exercises designed to solidify your understanding. This course is designed for beginner to intermediate Android developers who want to master mobile networking. No prior experience with Retrofit is required, though a basic understanding of Kotlin and Android development fundamentals is recommended.
